The machine seams fairly new, so one section of the lead screw should not be wore more than the rest. Is the axial play in the nut on the screw equal to the movement you were seeing on the cross slide? Fixing the mount and splitting the nut to remove backlash would seam like an easier fix.
Making new parts is fun but may not cure the problem.
I don't believe it's a backlash issue. The nut I have has a split in it already to remove backlash. I think it's probably a combination of poor mounting and poor design of the nut. I'm not making the new lead screw and nut. Ken offered to make a properly designed nut and lead screw so I accepted his offer. At least I'll know I'm working with good parts when I get the new parts.
The movement I was seeing is much more than the backlash I have.
